l M PROV EM' ENT I N SU LKY-PLOWS.

Specificationforming part of Letters Patent'No. 201,025, dated March 5,1878; application filed October 12, 1877.

To all whom it may concern:

Be itknown that I, JAMES LEIDY, of Galesburg, in the county of Knox andState of Illinois, have invented certain new and useful Improvementsin'Sulky-Plows; and I do hereby declare that the following is a full,clear, and'exact description thereof, which will enable others skilledinthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to' letters of reference markedthereon, which form a part of this specification.

Figure 1 is a perspective view of a sulkyplow embodying my invention,showing the parts in position for ordinary plowing. Fig. 2 is a rearelevation of Fig. 1, the mold-board partly broken away. Fig. 3 is arear'elevation, showing the plow inclined and themoldboard partly brokenaway. Fig. "4 is a top view of Fig. 1. Fig. 5 is a perspective view, anenlarged detail view of the device connecting the plow-beam to the axle;Fig. 6 is a rear elevation, showing the plow inclined oppositely to theposition shown at Fig.3. Fig. 7 is a vertical sectional view in the line.00 m in Fig. 2.

My invention relates to su'lky-plows; and consists, first, in certainimprovements in the construction of the devices by means of which theplow is leveled or inclined laterally, as oocasion requires; second, incertain improvements in the construction of the devices aforesaid andtheir connection with the levers, by means of which the plow isoscillated laterally; third, in a new combination of cranks or devicesoperating in connection with the plow, so that while one is oscillatedto incline the plowthe other aids in retaining it in position; fourth,in a new combination of devices, consisting of a yoke having bent orcurved ends, operating, in connection with the frame of the plow, tofacilitate the attachment and removal of the latter, all as hereinafterfully set forth and claimed.

Referring to the drawings by letters, A represents the axle or mainsulky-frame, con structed, and having wheels B B secured thereto, asshown and described in Letters Patent No. 17 4,686, granted to me March14, 1876, for improvement in cultivators.

C is a tongue or guide-pole, and G a bar secured upon the frame A, asshown in the drawings. The bar 0 supports a drivers seat, 0, andfoot-rests c.

D is the plow, and D its beam. E is a yoke. The yoke E is formed with acentral crank portion, E, to which the plow-beam is attached, ashereinafter described, and with one end, 6, straight, and its other end,0, curved or bent back upon itself, so that the ends 0 e may be insertedfrom the same direction between the parallel portions of the axle Abelow the journals of the wheels B, and secured therein by keepers e.

When the keepers e are removed, the yoke E may be removed from the axleby moving it toward the right-hand side of the frame A.

F is a saddle journaled on the yoke E, so that it may oscillate in avertical plane transversely with said yoke, and is secured by keepers ff, which permit of adjusting it in different positions on said yoke.

G is a rock-shaft, placed transversely to the yoke E and journaled inlugs g, which project upward from the saddle F, and has fixed upon eachof its ends a head, H H.

The plow-beam D rests upon and is secured to the rear head H by means ofbolts h, which bolts also secure a bar having arms I I projeotinglaterally from the plow-beam, so that when the bar I I is oscillated ina vertical plane transversely to the machine they will oscillate theplow on the rock-shaft G as an axis.

The head H is secured to the beam by bolts h, which also pass through aplate, h. The plate h has a series of holes for the reception of thebolts h, and the bar I I has also a series of holes, 6, by means ofwhich the plowbeam may be adjusted on the heads H H at different angles,in the evident manner. H is a brace from the plow-beam to the arm I.

J is a rock-shaft, with a crank, j, on one end, and is journaled in thebars 0 O, and may be adjusted and secured in different positionslongitudinally by keepers j. The outer end of the crank or arm j isconnected by a rod, j, with the outer end of the arm I.

K is a quadrant-shaped plate, loosely journaled on the shaft J, andhaving one limb projecting to form a hand-lever, k, and anotherprojecting to form an arm or lever, k,

and the are connecting them formed into a rack-bar, In, so that movementof the handlever 70 will simultaneously move the arm k and rack-bar k.The outer end of the arm k is connected by a link, L, to the outer endof the arm I.

L is a rack-bar resting upon the forward part of the frame A, and uponthe shaft J, so as to permit of the rotation of said shaft; or it may besecured to the guide-pole O, and is provided with notches, which receivea springpawl, I, attached to the lever k.

M is a hand-lever, secured to the rock-shaft J by a set-screw, m, sothat it may be used to oscillate the shaft J and hold it in differentpositions by engaging the spring pawl m, which is fixed upon saidhand-lever with the rack-bar k.

For ordinary plowing the left-hand wheel may be preferably, but notnecessarily, adjusted higher upon the frame A than the other wheel, asshown in Figs. 1, 2, and 3. With the hand-lever M engaged with therackbar k, the rock-shaft J becomes locked to the hand-lever k, andcauses the cranks or arms 70 and j to move simultaneously when thehand-lever k is oscillated, and thus permits the driver, by means ofsaid hand-lever k, to raise the bar I I in the same horizontal plane,and raise and lower the plow and fix it at different elevations byengaging the pawl l with the rack-bar L, for governing the depth ofplowing, and when desired to raise the plow above and out of the ground,as shown by dotted lines at Fig. 7.

The depth being adjusted, the driver may release the pawl of the leverM, and by oscillating said lever incline the plow to the right or left.hand, as shown at Figs. 3 and 6, until it is as desired, and then lookit in position by said pawl. It will be evident, also, that with theforegoing facility for adjusting the angle of the plow-sole laterally tothe surface of the ground the plow-sole maybe leveled or brought intohorizontal position when the wheels are running on the same horizontalplane, asin making backing-up furrows, or the right-hand wheel thelowest, as in ordinary plowing, regardless of whether the wheels areadjusted in the same or different horizontal planes on the frame A, thusenabling the operator to adjust and level the plow easily and quicklyfor making abacking-up furrow, or for ordinary plowing, or when depth ofplowing is changed, without moving from his seat, and as the plow passesalong, and without adjusting the wheels B on the frame A.

What -I claim as new, and desire to secure by Letters Patent, is-- 1.The bar I I, arranged to operate with the rock-shaft J, independentcranks j k, connect ing-rodsj L, and sulky A B, substantially as and forthe purpose specified.

2. The levers k and M and their respective cranks or arms k j, and linksj L, combined with the plow D,hinged to the sulky-frame, so as to havelateral oscillation, substantially as and for the purpose specified.

3. The combination of the laterally-hinged plow with two cranks or arms,j lo, to which the plow is connected, so that the one crank, j, may beoscillated to incline the plow, while the other, In, aids in retainingit in position, substantially as and for the purpose specified.

4. In combination with the frame A, the yoke E, having ends 0 a, bent orcurved, as described, to facilitate placing and removal in the frame A,substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
